Dose assessment in 2D and 3D mammography

Mammography remains the gold standard for breast cancer screening. Tn Algeria, Many medical imaging departments are currently moving to the digital modalities. However, digital mammography CR, DR and tomosynthesis are now available, allowing the radiologist to capture and manipulate the images so abnormalities can be seen more easily. Breast dosimetry is an important part of quality assurance program and an essential tool to optimize breast imaging procedures. The aim of this study is to compare two techniques; 2D and 3D imaging using a specific metric dose called Average Glandular dose (AGD) in mGy. Direct measurements on 32 patients were carried out at the public hospital CHU Beni-Messous with digital mammographic system TMS-Giotto TOMO including right and left cranio-caudal (CC) and medio-lateral oblique (MLO) views. Patient related data are represented by the range [min-max], average, median value and standard deviation of the measurements in the 2D and 3D modalities. The relative discrepancy between AGD (2D) and AGD (3D) was 55%. A particular attention must be given to the optimization of patient doses in mammography due to the latest recommendations formulated in TCRPl03.Mammography remains the gold standard for breast cancer screening.
